Dynamic Demographics

I found this presentation by Hans Rosling fascinating. He has dynamic graphs/charts that show how relationships between variables in different countries move over time. Birth rates vs. life expectancy, income vs. child mortality, etc. You can watch countries evolve over time.

Warning: This is a long video (20 minutes) and the file size is large (68 meg), so only try this if you've got a good broadband connection. If you want to just read the article look to this Discover Magazine article.

I had trouble getting the whole presentation to play online, but I could download a zip file and view on my PC in Quicktime after unzipping.
